Communication coordination and collision mitigation for multi-subscriber identity module devices

Abstract

This disclosure relates to systems, apparatuses, and methods for coordinating communication and avoiding and/or mitigating collisions for multi-subscriber identity module devices in a wireless communication system. A wireless device may coordinate communication associated with different subscriber identity modules and/or may mitigate collisions between communications associated with different subscriber identity modules. A network may provide information to improve coordination and/or mitigate collisions. A network may adjust paging schedules and/or provision of alert messages to improve coordination.
